Interpretation Introduction
Interpretation:
The mass in kilogram has to be converted to milligrams.
Concept Introduction:
Conversion-factor method is the one which can be used to convert one metric unit into another. With this, any unit can be converted to another unit by means of ratio. The ratio that is used to convert unit is known as conversion-factor. For example, one kilogram can be converted into gram by multiplying with 1000.
Answer to Problem 1.135QP
The given mass in kilogram is converted to milligrams as 5.91 ×106mg.
Explanation of Solution
Given mass in problem statement is 5.91 kg.
Since, 1kg=103g and 1mg=10-3g, we can use this to convert the above unit in micrograms,
5.91 kg × 103 g1 kg × 1 mg10-3 g=5.91×106mg
The given mass was converted into milligrams as shown above.

Answer to Problem 1.135QP
The given mass in milligram is converted to micrograms as 7.53 ×105μg.
Explanation of Solution
Given mass in problem statement is 753 mg.
Since, 1mg=10-3g and 1μg=10-6g, we can use this to convert the above unit in micrograms,
753 mg × 10-3 g1 mg × 1 μg10-6 g=7.53×105μg
The given mass was converted into micrograms as shown above.

Answer to Problem 1.135QP
The given megahertz is converted to kilohertz as 9.01 × 104 kHz.
Explanation of Solution
Given frequency in problem statement is 90.1 MHz.
Since, 1MHz=106Hz and 1 kHz=103Hz, we can use this to convert the above unit in kilohertz,
The given frequency was converted into kilohertz as shown above.

Answer to Problem 1.135QP
The given millijoule is converted to kilojoule as 4.98 × 10-4 kJ.
Explanation of Solution
Given energy in problem statement is 498 mJ.
Since, 1mJ=10-3J and 1kJ=103J, we can use this to convert the above unit in kilojoules,
498 mJ × 10-3 J1 mJ × 1 kJ103 J=4.98 × 10-4 kJ
The given energy was converted into kilojoules as shown above.
